Answer 1

2,5

Answer 2

Prim, giving another an answer isn't allowed my the CoC located here, have yourself a read, I suggest it: http://www.openstudy.com/code-of-conduct

Do you know how to solve equations? by adding/subtracting hem?

Answer 3

It confuses me greatly, but kind of, yes.

Answer 4

just put in the set of points and see what satisfies the equation

Answer 5

@andriod09 sure; wont happen again.

Answer 6

want me to walk you though it? @unheard

Answer 7

Yes please.

Answer 8

First thing is first, make sure the equations are lined up, like they are. So then you have: \[y > -3x + 3\] and \[y > 1x + 2\] now, you're trying to get "x", what do you do first?

Answer 9

Plug in one of the answer choices for x?

Answer 10

no, not yet. you need to isolate x, what do you do to the equation?

Answer 11

Subtract it from the number to the right?

Answer 12

What number to be precise? the -3x-1x, or 3-2?

Answer 13

-3x-1x

Answer 14

okay, what would you get?

Answer 15

-4x

Answer 16

okay, then what would you do?

Answer 17

I don't know.

Answer 18

What else do you have? you have this now: \[y > -4x + 3\] \[y > 2\] what do you do next?

Answer 19

3-2?

Answer 20

and you would get what?

Answer 21

1

Answer 22

which would leave the equation to what?

Answer 23

I don't know >.<

Answer 24

\[y>(-4x)+1\] is the problem now. now you plug in the answers, and find which one fits, and you would cancel out the y's, and get \[0>(-4x)+1\]

Answer 25

I'm confused.

Answer 26

wait, my fault. i fail. you don't cancel out the y's. (sorry!!!) take the 8 points, and work out the equations.

Answer 27

It's 2, 5 correct?
